Highlands aims to be a comprehensive improvement of Minecraft biomes, trees, and terrain. If you've ever felt bored exploring the world of Minecraft, this is your mod. In 1.8, Highlands is going into uncharted territory, where no biome mod has gone before. It's been designed from the ground up with features from the old Highlands as well as brand new biomes and trees. Highlands also gives you an incentive to explore into uncharted territory, whether to search for the perfect mountain to build a base on, to complete your botanical garden, or to search for more lucrative mining opportunities.
Features:
18 new biomes!
8 trees, all with their own wood, leaves and planks!
6 small plants!
Custom world type and mountain generation!
Fully compatible with customized world settings!
Settings to disable biomes you don't want!
Biome rarity fix!
Ore generation changes per biome!
Forest generation based on height!
Improvements to vanilla biomes!
